BURNER FOR CRUDE OIL OR OTHER LIQUID FUEL.

SPECIFICATION forming part of Letters Patent No. 443,342, dated December 23, 1890.

Application filed June 28, 1889. Serial No. 315,876. (No'modeL) To all whom it may concern.-

Be it known that I, THEODORE WILLI, of Dayton, in the county of Montgomery and State of Ohio, have invented a new and useful Improvement in Burners for Crude Oil or other Liquid Fuel, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure I is a vertical sectional view of my improved burner with the vaporizer in position; Fig. II, a detail view of the vaporlzer Fig. III, a cross-section of the vaporizer through the line 0;; Fig. IV, a cross-section through the line y; Fig. V, a view of the concentrator. Fig. VI is a vertical central section of the vaporizer in Fig. II.

My invention relates to lmprovements 1n appliances for vaporizing and burn ng crude oils; and its object is to provide a simple, inexpensive, safe, and efficient device whereby liquid fuel of every description may be thoroughly consumed and the heat readily utilized for any desired purpose.

The invention consists of a movable apparatus, in which the oil is first subjected to close contact with a vaporizer, by which it is quickly convertedinto vapor, which is superheated as it ascends to the burner in attenuated jets, in which form it rapidly combines with the oxygen of the atmosphere and produees a flame of intense heat.

The peculiar construction of the device will be readily understood by reference to the accompanying drawings, in which A designates the bodv of the burner, having a central subconical recess a to receive the vaporizer B, which is closely fitted therein.

The said vaporizer consists of a solid metallic plug having the lower portion Z) of the shape of a frustum of acone to fit 1nto the recess Ct and form therewith the oil-chamber H. The said lower portion 1) has surrounding it the annular recess D, which when the vaporizer is in place forms a heating-chamber for the oil. The upper-part I) of the vaporizer projects above the burner A and serves still further to spread and heat the ascending burning vaporized oil.

One or more small segments are cut from the vaporizer between the recess or chamber D and the lower end of the vaporizer to permit the oil in limited quantity to pass into the annular recess D. These out-away parts form ducts C When the vaporizer is in place to permit the oil to ascend from the chamber II to the recess D. A suitable numberof vaporducts E are formed by simply grinding or cutting small segments from the body of the vaporizer between the recess Dand the shoulder b of the vaporizer,which shoulder is flush with the adjoining part of the floor of the burner A. The supply of oil is regulated by a valve G in the pipe leading from the oilreservoir, which pipe g has its upper end threaded and fitted into an opening in the 'burner and communicates with the chamber H.

The operation of the device is easily described. When the valve is opened, the oil ascends into the cup of the burner, Where it is ignited. The vaporizer and burner soon become heated, and the oil being ditfused in athin film on the surface thereof becomes rapidly converted into vapor, which is superheated in its passage in the form of thin jets to the burner. 'Being thus doubly prepared, it instantly combines with the air and is thoroughly consumed. The oil ascends from the pipeg to the chamber H, and thence through the ducts O to the annular recess D, where it is heated both by the vaporizer and burner. Thence it ascends in films through the ducts E, and there ignites and passes up the surface of the part b of the vaporizer surrounding the same. If desired, aconcentrator (see Fig. V) may be employed to confine the heat to narrow limits, or the contrary effect may be produced by placing a cap over the burner, so formed as to disperse the heat. In practice it is found that this process effectually utilizes the various constituents of oils, and no provision is required to dispose of residue. If extraneous matter should be introduced with the oil, it will be retained in the recess II below the vaporizer, and any accumulation may be easily removed.

The various advantages of this device are worthy of special notice. It can be made of all sizes at a trifling expense. Any required number may be placed in a series and used to advantage in the fire-box of a stove or in a furnace, and any one or more may be disconnected by simply turning a valve. By employing afiexible supply-pipe the burners may be easily moved from place to place and made available whenever it becomes desirable or expedient to vary the direction and application of the heat.

What I claim as new is 1. The combination, with the cup-shaped burner provided with a central conical or tapering recess in its floor and the oil-supply pipe opening into the bottom of said recess, of a solid metallic vaporizer having its lower or base part fitted into said recess in such manner that an oil-chamber is formed below it therein, and provided with a surrounding annular recess in said lower part to form a heating-chamber with the burner, and suitable ducts extending from the oil-chamber below the burner to the said recess and from the recess to the floor of the burner, substantially as specified.

In testimony that I claim the foregoing I 30 have hereunto set my hand, this 11th day of June 188.), in the presence of witnesses.

THEODORE WILLT.
